Holes patched from rodents

Trimble near Rutland, Cincinnati OH

Description

I have been hearing running and scratching in my walls and have caught several mice. Exterminators have come to set traps and bait boxes but I need the holes inside the home filled/closed up. I know where most of them are but I’m not sure of the most effective way to deal with this outside of using steel wool some holes are bigger with may require more work. I would like this done or at least started asap.
